Some Supervision Required: Incorporating Oracle Policies in Reinforcement Learning via Epistemic Uncertainty Metrics

no code implementations22 Aug 2022 Jun Jet Tai, Jordan K. Terry, Mauro S. Innocente, James Brusey, Nadjim Horri

In the case of using an oracle policy, it can be unclear how best to incorporate the oracle policy's experience into the learning policy in a way that maximizes learning sample efficiency.

Differential radial basis function network for sequence modelling

no code implementations13 Oct 2020 Kojo Sarfo Gyamfi, James Brusey, Elena Gaura

We propose a differential radial basis function (RBF) network termed RBF-DiffNet -- whose hidden layer blocks are partial differential equations (PDEs) linear in terms of the RBF -- to make the baseline RBF network robust to noise in sequential data.

K-Means Clustering using Tabu Search with Quantized Means

no code implementations24 Mar 2017 Kojo Sarfo Gyamfi, James Brusey, Andrew Hunt

Moreover, the difficulty in parameter selection in the existing TS approach does not make it any more attractive.

Linear classifier design under heteroscedasticity in Linear Discriminant Analysis

no code implementations24 Mar 2017 Kojo Sarfo Gyamfi, James Brusey, Andrew Hunt, Elena Gaura

Under normality and homoscedasticity assumptions, Linear Discriminant Analysis (LDA) is known to be optimal in terms of minimising the Bayes error for binary classification.
